Last night, singer Mariah Carey tweeted a photo of her husband Nick Cannon laid up in a hospital bed in Aspen, along with the news that he was hospitalized with a "mild" form of kidney failure.

"Please pray for Nick as he's fighting to recover from a mild kidney failure," she tweeted early Wednesday morning.

In a subsequent tweet, she added: "We're trying to be as festive as possible under the circumstances but please keep Nick in your thoughts because this is very painful. They tried to kick me out of the hospital but here I am pon de bed with Mr. C."

So what is "mild" kidney failure, you ask? Mariah might be referring to Acute Renal Failure, or the beginning stages of kidney failure. But then again, Nick might not be in kidney failure at all (Nick and Mariah are such drama queens).
